Rotate a Photo?

There are three ways to do this: (1) in the Library module, go under the Photo menu and choose either Rotate Left or Rotate Right, as shown above, (2) use the keyboard shortcut Command-[ (PC: Ctrl-[) or Command-] (PC: Ctrl-]; those are the bracket keys, located just to the right of the letter P on your keyboard), or (3) in the thumbnail Grid view in the Library module, by default there are two little rotation arrows in the bottom corners of each thumbnail’s cell (if you don’t see them, move your cursor over the cell of the image you want to rotate and they should appear. If they still don’t appear, press Command-J [PC: Ctrl-J] to bring up the View Options dialog and, under Compact Cells Extras, make sure the Rotation checkbox is turned on, and you should be good to go). That being said, your best bet is still the keyboard shortcuts simply because they’re the fastest, and they work in the Library or Develop modules.
